Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
The probability that there is at most one purple marble is 0.9701.
<h3>What is the probability about?</h3>
Probability is a term that connote the possibility of an event or something occurring or not.
Note that it is one that is based on the level of occurrence that can be seen in a random event.
Based on the fact that there is a bag that has eight yellow marbles, nine green marbles, three purple marbles, and five red marbles, the probability that there is at most one purple marble is 0.9701.
